Kingdom Hearts 4 takes place in a new world called Quadratum, and we've got some further details regarding the game. While Quadratum might look like Shibuya in Tokyo, it's meant to look like an afterworld, according to creator Tetsuya Nomura. Nomura added that the room Sora wakes up in during the trailer is another area called Minami-Aoyama, in Tokyo.
"That room will be the base for the early part of the game," he revealed.
"From each of our perspectives, our perceptions change. In [mobile game] Kingdom Hearts Union χ, the Master of Masters said something along those lines.
"From Sora's perspective, Quadratum is an underworld, a fictional world that is different from reality. But from the point of view of the inhabitants on the Quadratum side, the world of Quadratum is reality, and the world where Sora and the others were is the other side, the fictional world.
"I think the theme of this project will be the contrast between those who are in such different positions."
Various worlds collide, and we can see some differences, like when Donald and Goofy look for Sora and Sora seems realistic. However, Nomura adds that he likely doesn't look like that for the entire game.
"Donald and Goofy are looking for clues about Sora in the original world," he explained. "All the real worlds before the title display [in the trailer] are all Quadratum segments, and Sora will look realistic, but if he can return to the original world, he will look like Donald and Goofy with shaders like Donald and Goofy."
There's no official release date or window yet for Kingdom Hearts 4, and it's expected to take another two years for completion.
